Cake wrapping device

ABSTRACT

The yarn cake wrapping device comprises a tubular member passing through an arm which is pivotally mounted near one end so that it can be swung from one side of the mount to the other. A rigid tubular cake wrapper is placed in the tubular member and a cake of yarn is disposed about the tubular member and wrapper while the arm is in the load position. The upper end of the wrapper is drawn down about the cake and the arm is swung to a horizontal position on the other side of the mount to discharge the cake. The free end of the wrapper is then drawn over the second end of the cake.

HANS J. DESSAUER ,BYW 11$ AYTOR/VEY CAKE WRAPPING DEVICE BACKGROUND OFTHE INVENTION type of device a tubular wrapper is placed over acylindrical 1 stock and its base member, a cake of yam is placed on thestock and the free ends of the wrapper are drawn about the cake. Otherdevices employ means for passing the tubular wrapper through the annularmember of the cake. Difficulties may occur during subsequent processingif the wrappers are creased or overlap.

SUMMARY OF THE INVENTION It is an object of the present invention toprovide a simple mechanical device for wrapping annular cakes of yarn.

It is another object of the invention to provide a device for insertinga tubular wrapper through the annular member of the cake.

It is a further object of the invention to provide a device forinserting a tubular wrapper through the annular member of a cake ofyarn, drawing the wrapper over the upper end and the outside of the cakeand then discharging the cake in order that the wrapping may becompleted.

Other objects and advantages of the present invention will be apparentfrom following detailed description taken in conjunction with theaccompanying drawings.

The cake wrapping device comprises a base with an upright member, an armpivotally mounted at the upper end of the upright member and adapted tobe swung from one side of the upright member to the other. A tubularmember passes through the arm, extending above and below the arm fordistances on one side at least not exceeding the height of the cake tobe wrapped.

A rigid tubular wrapper is inserted into the tubular member, a cake ofyarn to be wrapped is placed on the device so that the tubular memberpasses through the opening of the cake, and the free end of the wrapperis drawn over the top of the cake and down the outside. The arm is thenswung to the other side of the upright member to discharge the cake. Theremaining free end of the tubular wrapper is then drawn over the end andthe outside of the cake.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows the device and thetubular wrapper.

FIG. 2 shows the device in the load position with a cake of yarn andtubular wrapper in place.

FIG. 3 shows the wrapper drawn over the upper end and the side of thecake.

FIG. 4 shows the device swung to the discharge position and thedischarged cake.

FIG. 5 shows the completion of the wrapping of the cake.

FIG. 6 shows a completely wrapped cake.

FIG. 7 shows a similar cake with the outside not completely covered.

DESCRIPTION OF THE PREFERRED EMBODIMENT The cake wrapper shown in thedrawings comprises a base member 1 and an upright member 2 with arm 3attached to the upright member by pivotal mounting 4. The ends of theupright member 2 and arm 3 are cut at an angle of about 45 at 5 and 6,respectively, to limit movement of the pivoted arm in one direction.Brace or stop 7 limits movement of the arm in the other direction.

Tubular member 8 passes through arm 3, extending outwardly from the armon each side a distance equal to or somewhat less than the height of thecake to be wrapped. The outside diameter of the tubular member isslightly less than the diameter of the annular member of the cake to bewrapped. By dictionary definition a tubular member is a hollow cylinder.

With arm 3 in the position shown in FIG. 1 a rigid tubular cake wrapper9, which may be of the pleated or the corrugated type, is inserted intotubular member 8. The arm is swung to the load position shown in FIG. 2.The wrapper is positioned in the tubular member so that when yarn cake10 is placed on arm 3 with tubular member 8 extending through the 5annular member of the cake, as shown in FIG. 2, the portion of thetubular wrapper extending above the top of the cake is sufficient tocover the top and a portion of the outside of the cake when that portionof the tubular wrapper is folded down as shown in FIG. 3. Arm 3 is thenswung to the release position to discharge the partly wrapped cake asshown in FIG. 4 and the free end of the tubular wrapper is folded downto completely cover the cake as shown in FIGS. 5 and 6.

If it is desired to cover only the ends of the cake a tubular wrapper ofappropriate length may be used to produce the wrapped cake shown in FIG.7.

If desired, a roll of tubular wrapping material may be positioned onbase member 1 below tubular member 8 when it is in the position shown inFIG. 1. Suitable lengths of tubular wrapper, which may be perforated topermit tearing instead of cutting, may be drawn off from the roll andinserted into tubular member 8 and the remainder of the process carriedout as described above.

It is to be understood that changes and variations may be made in thepresent invention by one skilled in the art without departing from thespirit and scope thereof as defined in the appended claims.
